When resolving changed conf file conflicts, dpkg ignores choice to view diffs

[Bogdan Harjoc]

I installed some updates using the "updates are available" GUI and when updating rsyslog, a GUI prompt for resolving a changed /etc/rsyslog.d/50-default.conf appeared, and I picked "view diff between versions", however the update process continued, saving the dist one as /etc/rsyslog.d/50-default.conf.ucf-dist and leaving the existing one unchanged.

I guess the "view diff" was the expected behavior here.
